Please choose all that are correct. Select one or more: O a. To maintain the same acceleration, when the force applied is halved, mass must also be halved O b. If there is only one force acting on an object, that force is equal to the net force O c. A force cannot be negative O d. An object flying through vacuum does not have a normal force acting on O e. Friction is a fundamental force O f. An...

True/False Indicate whether the sentence or statement is true or false. 1. The inertia of mass is directly proportional to its velocity. 2. When a constant force is applied to an object,acceleration remains the same. 3. Action and reaction forces have the same direction. 4. When the force acting on an object is doubled, the effect on the acceleration of the object will be tripled. 5. When the normal force is doubled, the coefficient of friction is quadrupled acceleration than...

You have a crate full of books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to start moving? (b) Once...

A cat is in a box, being pulled in a straight line at a constant speed. Which of the following statements is true about the net force acting on the cat? A. It is zero. B. It is equal to the cat’s weight. C. It is less than the cat’s weight but greater than zero. D. It is equal to the magnitude of the force of friction.

Why should the block move at constant velocity (due to the pull of the hanging weight) when finding kinetic friction (procedure 2). Constant velocity means zero acceleration, means Tension = Friction force Because we cannot measure acceleration. if velocity is not constant, the tension in the string wil become zero. Because acceleration will add another force pulling the block (in addition to the tension in the...

A horse harnessed to a wagon refuses to pull citing Newton’s third law of motion as grounds for not being able to possibly be able to move the wagon. The horse, incorrect in his reasoning, can pull the wagon because: - the law only applies to static cases -after it gives a jerk and the wagon is moving, the horse’s pulling force will be greater than the reaction to this force - the action and reaction forces are acting on...
